A couple years ago I told my Daughter (kids=gullible) jokingly that I was 23. On my Bday a couple days later I got a homemade card that my wife helped her make that said "Happy 23rd Birthday Daddy!". Apparently she had told her i was 23 and the Mrs. went right along with it.
You're only as old as you feel anyway, right! Have a good one buddy!!!
